The embodiment of energy saving and environmental protection technology in aluminum-plastic co-extrusion doors and Windows

Requirements for the application of energy-saving and environmental protection technology in aluminum-plastic co-extrusion doors and Windows: In order to rationally apply the application of aluminum-plastic energy-saving materials, the design of aluminum-plastic energy-saving doors and Windows should consider many factors. According to the construction practice of aluminum-plastic doors and Windows, there are three ways of heat transfer in the building system, including conduction, convection and radiation.

By restraining these heat transfers, aluminum-plastic doors and Windows can achieve energy-saving effects, so how to restrain heat transfer has also become a key point. Heat preservation and insulation technology can reduce the transfer of heat to achieve the purpose of energy saving of the building external structure.

Application analysis of energy-saving glass in aluminum-plastic co-extrusion doors and Windows. In the structure of doors and Windows, the area of glass accounts for 80% of the entire window, in order to achieve good energy saving effect, the selection of glass has a strong importance. In China's construction industry, the operating model has always been a low level, the process is not detailed and specific, because of this, the application of building doors and Windows has been only to ensure the most basic performance, and the energy-saving, sound insulation, convenience and beautiful functions of building doors and Windows have not been really applied.

Usually, China's traditional building doors and Windows are single-layer glass, because the use of single-layer glass performance is very low, can not block far infrared and solar radiation. For example, in the winter in the northern regions of the outdoor is extremely cold, and the indoor temperature difference is very large, because the use of single-layer glass, indoor heat will also be seriously lost through the gaps in the Windows and doors; In the summer, due to the use of single-layer glass, the heat radiated by the sun will radiate through the glass to the interior of the building, causing the temperature of the interior of the house to exceed the outdoor temperature.

Due to the occurrence of these situations, the living quality of households is greatly affected, so in order to fundamentally achieve the skill goals of building house doors and Windows, and improve the insulation and thermal insulation function of the house itself, the appropriate energy-saving glass should be selected first.
